SAFETY CHECK-OUT
After correcting the original service problem, perform the following safety checks before releasing the set to the customer:
1. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder
splashes and bridges.
2. Check the interboard wiring to ensure that no wires are
“pinched” or contact high-wattage resistors.
3. Check that all control knobs, shields, covers, ground straps,
and mounting hardware have been replaced. Be absolutely
certain that you have replaced all the insulators.
4. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point
them out to the customer and recommend their replacement.
5. Look for parts which, though functioning, show obvious
signs of deterioration. Point them out to the customer and
recommend their replacement.
6. Check the line cords for cracks and abrasion. Recommend
the replacement of any such line cord to the customer.
7. Check the B+ and HV to see if they are specified values.
Make sure your instruments are accurate; be suspicious of
your HV meter if sets always have low HV.
8. Check the antenna terminals, metal trim, “metallized”
knobs, screws, and all other exposed metal parts for AC
Leakage. Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground
and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or
RCA WT-540A. Follow the manufacturers’ instructions to
use these instruments.
2. A battery-operated AC milliammeter. The Data Precision
245 digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so analog meters must have an accurate lowvoltage scale. The Simpson 250 and Sanwa SH-63Trd are
examples of a passive VOMs that are suitable. Nearly all
battery operated digital multimeters that have a 2 V AC
range are suitable. (See Fig. A)

Precautions
Warning on power connections
• Use the supplied power cord. If you use a different power cord,
be sure that it is compatible with your local power supply.
• Before disconnecting the power cord, wait at least 30 seconds
after turning off the power to allow the static electricity on the
screen’s surface to discharge.
• After the power is turned on, the screen is demagnetized
(degaussed) for about a few seconds. This generates a strong
magnetic field around the screen which may affect data stored
on magnetic tapes and disks placed near the monitor. Be sure to
keep magnetic recording equipment, tapes, and disks away
from the monitor.
Installation
Do not install the monitor in the following places:
• on surfaces (rugs, blankets, etc.) or near materials (curtains,
draperies, etc.) that may block the ventilation holes
• near heat sources such as radiators or air ducts, or in a place
subject to direct sunlight
• in a place subject to severe temperature changes
• in a place subject to mechanical vibration or shock
• on an unstable surface
• near equipment which generates magnetism, such as a
transformer or high voltage power lines
• near or on an electrically charged metal surface
Maintenance
• Clean the screen with a soft cloth. If you use a glass cleaning
liquid, do not use any type of cleaner containing an anti-static
solution or similar additive as this may scratch the screen’s
coating.
• Do not rub, touch, or tap the surface of the screen with sharp or
abrasive items such as a ballpoint pen or screwdriver. This type
of contact may result in a scratched picture tube.
• Clean the cabinet, panel and controls with a soft cloth lightly
moistened with a mild detergent solution. Do not use any type
of abrasive pad, scouring powder or solvent, such as alcohol or
benzene.
Transportation
When you transport this monitor for repair or shipment, use the
original carton and packing materials.
Use of the tilt-swivel
This monitor can be adjusted within the angles shown below. To
find the center of the monitor’s turning radius, align the center of
the monitor’s screen with the centering dot on the stand.
Hold the monitor at the bottom with both hands when you turn it
horizontally or vertically. Be careful not to pinch your fingers at
the back of the monitor when you tilt the monitor up vertically.

Technical Features
Preset and user modes
When the monitor receives an input signal, it automatically
matches the signal to one of the factory preset modes stored in the
monitor’s memory to provide a high quality picture at the center
of the screen. (See Appendix for a list of the factory preset
modes.) For input signals that do not match one of the factory
preset modes, the digital Multiscan technology of this monitor
ensures that a clear picture appears on the screen for any timing in
the monitor’s frequency range (horizontal: 30
– 130 kHz (CPD-
G520), 30 – 110 kHz (CPD-G420), vertical: 48
– 170 Hz). If the
picture is adjusted, the adjustment data is stored as a user mode
and automatically recalled whenever the same input signal is
received.
Note for Windows users
For Windows users, check your graphics board manual or the
utility program which comes with your graphics board and select
the highest available refresh rate to maximize monitor
performance.
Power saving function
This monitor meets the power-saving guidelines set by VESA,
E
NERGY
S
TAR, and NUTEK. If no signal is input to the
monitor from your computer, the monitor will automatically
reduce power consumption as shown below.
* Figures reflect power consumption when no USB compatible
peripherals are connected to the monitor.
** When your computer enters power saving mode, the input signal is
cut and NO SIGNAL appears on the screen before the monitor enters
active off mode. After a few seconds, the monitor enters power saving
mode.
*** “Deep sleep” is power saving mode defined by the Environmental
Protection Agency.

Troubleshooting
Before contacting technical support, refer to this section.
If thin lines appear on your screen
(damper wires)
The visible lines on your screen especially when the background
screen color is light (usually white), are normal for the Trinitron
monitor. This is not a malfunction. These are shadows from the
damper wires used to stabilize the aperture grille. The aperture
grille is the essential element that makes a Trinitron picture tube
unique by allowing more light to reach the screen, resulting in a
brighter, more detailed picture.
On-screen messages
If there is something wrong with the input signal, one of the
following messages appears on the screen.
If NO SIGNAL appears on section
1
This indicates that no signal is input from the selected connector.
If OUT OF SCAN RANGE appears on line
